I've encountered this before.

First try to search through the xml files you edited last for strange structure or anything that looks like it does not belong there. The xml schema follows a structure and when this error occurs that structure is damaged to the point that it includes text from other files or fragments of code from adjacent modules.

Next, look for the main files like eq2ui_mainhud.xml and the next include in the chain of eq2ui.xml which would be eq2ui_custom.xml. That file could be corrupted or a module it includes.

Just some tunnels to go down. Good luck.
